4 Claims.

This invention relates to a dry cleaner for the hands. More specifically the invention relates to a hand and skin cleaner that may be eifectively used for cleaning without the use of water, soap or towels.

The primary object of the present invention is to provide a composition which may be used directly for cleanin the hands.

There are many situations when and where it is not possible or desirable to clean the skin, particularly the hands, with water, soap and towels.

The cleaning-composition of the present invention is well suitedfor cleaning under. such circumstances because the composition dissolves and absorbs the dirt or staining substances and can be easily removed'i'rom the skin or hands after the dirt has been absorbed. Furthermore the composition is not harsh to delicate skin and will not injure the skin, but protects it against chapping.

With these and other objects and features in view, the invention consists -in the improved cleaning composition hereinafter described and particularly defined in the claims The cleaning composition is'preferably in the form of a liquid which can be spread over the skin and by working it into contact with the dirt and soiling substances it acts to dissolve and absorb such substances. Then further working of the composition on the skin evaporates solvent in the composition to convert it into a dry, crumbly material which can be readily brushed from the skin to remove the dirt and soiling substances with it.

A composition suitable for dry cleaning has the following composition:

Percent by volume Egg albumen 39 Distilled water 39 Potassium coconut oil soap in solution having specific gravity of 1.028 7.8 Glycerin 1.5 solution of sodium stearate 1.0

10% solution of sodium hexametaphosphate 11.7 Antioxidant -..Trace to .1

The proportion of glycerin in the, abov composition may be varied from 1% to 2% and the proportion of potassium coconut oil soapmay be varied from 6.8% to 8.8% and still give asatisfactory product. When the glycerin, and soap proportions are varied the amount of water must be varied accordingly to give the 100% composition. 1 p i The odor of this composition may bemodified by the use of a perfume, or deodorant, such as the Du Pont FS Nos. 1, 2, 3 and'4.

The composition may be colored by a suitable dye, such as the Du Pont Pontachrome Blue or the FCR Yellow. v

A suitable antioxidantfor this composition may be hydroquinone, maleic acid, or gum guaiac also known as guaiacum. The glycerin in the product also acts as an antioxidant. v

The albumen forms the body of the material for absorbing the oils, dirts and soiling materials on the skin. The potassium and sodium soaps. are detergents and the sodium hexametaphosphate is a good detergent and clarifying agent. The glycerin is a solvent and acts effectively in protecting theskin from any reaction of the soap used. The albumen is in water solution and the water solution from the albumen, as well as the soaps and hexametaphosphate, is evaporated as the material is worked'and rubbed against the skin for dissolving the dirt or soiling substances.

In order toinake the composition the albumen is first thoroughly dissolved in water, then potass'ium soap. is added and the mixture dissolved inthe gLvcerin' Sodium soap and sodium hexametaphosphate are then added to complete the composition. The mixture of materials is a cloudy mixture until the hexametaphosphate is added. Thereupon a clear solution is formed.

It isimportant that the; percentage of glycerin should not be more than 2% because an excess of glycerin prevents thedrying' of the composition so that. it may be easily brushed oifthe The preferred form of the invention having been thus described, what is claimed as new is:

Y 1. A cleaning composition comprising about 39% by volume of egg albumen, about 39% by volume of distilled water, about 7.8% by volume of a potassium, coconut oil soap solution having .a specific gravity of about 1.028, about 1.5% by volume of glycerin, about 1% by volume of a 20% solution of sodium stearate, and about 11.7% by volume of a 10% Solution of sodium hexametaphosphate. I I

2. A cleaning composition comprising about 39% by volume. of -egg albumen, about 39% by volume of distilled water, from aboutv 6.8% to about 8.8% by volume of a potassium coconut oil soap solution having a specific gravity of about 1.028, from about 1% to about 2%'by volume of glycerin, about. 1% by volume of a 20% solution of sodium stearata and about 11.7% by volume of a. 10% solution of sodium hexametaphosphate.

3. A cleaning composition as defined by claim 1 ,4. Aicleaning composition as defined by claim2 containin from a trace to about 0.1% by volume of an antioxidant selected from the group 'con sisting of hydroquinone, maleic acid, and gum guaiac.
